2023 Study Architecture Student Showcase - Part XXVIII

In Part XXVIII of the 2023 Study Architecture Student Showcase, each project focuses on the construction and architecture fields’ roles in climate change. The presented student theses and designs present a tangible solution to address climate change with proposals ranging from using materials including mass timber and “Hempbrick” to systematic changes such as incorporating decay into the designs and introducing sustainable product life cycles. Overall, the projects advocate for reducing waste to support long-term sustainable practices.

Reconstituting Rubble by Andrew Griffin, M.Arch ‘23
University at Buffalo | Advisors: Christopher Romano & Miguel Guitart

Five hundred and thirty-four million tons of construction and demolition debris are generated by the United States every year. This debris is anonymously moved away, invisible to most, to distant landfills far removed from its origin to lie dormant at the presumed end of its life. This demolition is a natural and necessary part of our current economic cycle, the permanence of the buildings we design is too often overstated. In a time when environmental issues plague the industry, simply discarding material is no longer a reasonable long-term option. Perhaps the scope of an architect’s involvement should extend into a building’s afterlife. Reconstituting Rubble proposes an adjustment to the material flow of building debris after demolition, advocating ways of transforming architectural rubble to develop building procedures that integrate waste-bound materials into new architecture. Drawing from new innovations and old technology, the project strives to lay out building end-of-life processes to divert would-be discarded material into new building assemblies.

This research looks at demolition rubble as a continuous stream of usable material in need of transformation. The proposed process steps involve demolishing, cataloging, refining, assembling, and reconstituting. The eventual result of this process examines the qualities of rubble, the roughness, the irregularity of its texture, shape and size. These are all traces of its past and show the immense effort it took to become reconfigured remains.

Banished Into Existence: Agritecture at The Intersection of Architecture and Agriculture by Yan Ferris Konan, M.Arch & M.Red ‘23
University of Maryland, College Park | Advisor: Michael T. Ezban

Building operating emissions account for 28% of global greenhouse gas emissions while building components account for 11%. To mitigate these effects, we must reduce the carbon footprints of construction activities, building materials, and sequestering carbon dioxide in forests and farmland. Industrial hemp is a solution to all these challenges. Hemp is a carbon-negative crop, absorbing more carbon dioxide than trees, and thus represents a unique sequestration opportunity. By using hemp as a construction material, we can improve the thermal efficiency of our buildings, therefore reducing operational carbon. Finally, by substituting Hempbrick, a mixture of hemp and various binders, for more carbon-intensive materials, we can reduce the embodied carbon of the built environment. This thesis proposes a productive hemp landscape that will be open to the public as an agritourism destination. The project will raise public awareness about hemp cultivation as an agricultural opportunity and demonstrate the potential of hemp as a construction material, highlighting its multiple possible contributions to tackling the climate crisis.

The Intersection, located in Beltsville, Maryland, is a Productive Hybrid Hemp Farm with a visitor center, a manufacturing facility, a multipurpose Classroom, and office seating on two floors to serve as a demonstration and educational hub for Prince George’s County. This proposal aims to educate the public on the opportunities of this insulating material known as “Hempbrick.”

The site is divided into Three Parcels totaling 77 Acres. Parcel 1: Baltimore Avenue (15.5 Acres). Parcel 2: Baltimore Avenue (50 Acres). Parcel 3: Rhode Island Avenue (11.5 Acres). The Farm’s primary goal is cultivating and harvesting Hemp for industrial applications. There will also be a manufacturing facility where the hemp will be decorticated into bast and hurd fibers required to produce Hempbrick. In addition, there will be a Visitor Center where the public will learn about the benefits and processes of hemp. Tenants from The University of Maryland extensions have already expressed an interest in leasing office spaces to further their research on hemp and its advantages.

Forest to Framework by Eleanor Selzer, M.Arch ‘23
University of Southern California | Advisor: Sascha Delz

With the construction industry accounting for roughly 40% of all global carbon emissions, a clear and vast opportunity exists within the Architectural and Construction industry to enact real change in fighting the climate crisis. This change, as seen from a top-down perspective within the supply chain, could include material substitutions, technology innovation and implementation, and independence from non-renewable energy sources. These initiatives geared up in practice in recent years, but the industry is lagging behind if we are to make any real impact on our emissions and meet global climate goals. 

The UN projects that there will be roughly 2.3 billion new urban dwellers by 2050. All of these new residents will require an enormous amount of infrastructure to sustain this influx, most importantly housing. Most low-to-medium-rise housing buildings are constructed using timber products, and so there is a profound opportunity to exploit this demand for new development as a means to mitigate the climate crisis and create a carbon sink within our cities. 

When designers consider viable substitutions that are readily available, mass timber products are the top contenders. The opportunity to sequester carbon from the atmosphere while also providing a structurally sound, lightweight, and aesthetic material makes wood a clear solution for fighting climate change. 

It is vital for timber products used in the construction industry to be sourced from sustainable-certified forest lands to ensure that deforestation of green reserves is mitigated and there is a guarantee of a true renewable resource. The existing supply chain, however, is not vertically integrated, and it follows the cradle-to-grave pipeline, where building materials will most likely end up in landfills following demolition. As a solution to climate impacts, the industry must introduce a closed-loop product life cycle system following the cradle-to-cradle ideology. 

This sustainable wood products cycle requires all players across the supply chain to redefine how they purchase, distribute, design and use mass timber products. The main priorities within this sustainability product cycle are ensuring the increase in sustainable land management practices, growing the demand for sustainably harvested and produced mass timber products, updates to the building codes to mandate the use of these products and creation of deconstruction and reusable toolkits that can be adopted into standard design and construction practices.   

This project seeks to re-frame the framework of sustainably harvested mass timber products and show how they can be utilized in design practices to maximize flexibility, incremental growth, reuse and adaptability. Specifically this framework is applied to an affordable housing cooperative model located in Venice Beach, Los Angeles, comprising of flexible and deconstructable mass timber modules. 

This project received the USC Master of Architecture Social & Environmental Dimensions in Directed Design Research Award – In recognition of the most outstanding graduate final degree project exploring social, cultural, and environmental concerns.

Heteromorph by Grégoire Gaudreault, M.Arch ‘23
University of Montreal | Advisor: Andrei Nejur

On a global scale, more than one billion people live in precarious housing situations, many construction materials are regularly sent to landfill sites or, worse, burned. However, these rejected materials represent a richness whose reallocation would lead to a significant economy of resources. Therefore, reusing materials from the construction industry could be part of the solution. This thesis project attempts to establish an architectural response to these challenges. Specifically, the proposed solution involves a constructive system for assembling temporary shelters using a diverse range of reclaimed and heterogeneous materials. The research focus of this thesis primarily revolves around utilizing digital technologies to discover new solutions to social and urban problems, while promoting the development of innovative construction methods that aim to reduce the environmental impact of architecture.

In a conventional architectural project, the materials used are directly linked to the envisioned form conceived during the design process and are typically integrated toward the end of the project. The proposed workflow seeks to invert this logic: reclaimed materials are used as inputs to imagine the shape of a shelter. Available resources dictate the morphology and composition of the projected form. More specifically, the proposed digital solution is based on an algorithm created using visual programming software, which enables the revalorization of materials recovered from waste in the construction industry. Any shape obtained through this method is composed of a configuration of 10 typical triangles, resulting from a combination of three specific edge lengths. These triangles can be constructed using either three linear elements or a single planar element, thereby expanding the range of possible materials. Low-tech metal nodes are utilized to connect these elements, facilitating the assembly and disassembly of the system. This flexibility allows for several variations or even partial or complete reconfiguration of the initial shape. In addition, the proposed system’s evolutive character encourages its components’ re-employment to limit its environmental impact.

An Architecture of Decay: Addressing Building Waste Through Biologically Integrated Architecture by Carson Stickney, M.Arch ‘23
Lawrence Technological University | Advisors: Scott Shall (Chair), Dan Faoro (Member) & Sara Codarin (Member)

There is a dissonance within architectural practice between buildings designed to be permanent, and the inevitability of building impermanence. This produces unusable waste at the end of a building’s life cycle. Materials are designed to become obsolete and replaced over time, leading to additional waste during a building’s inhabitance. Construction conventions value the low-cost consumption of resources such as concrete and metals over their effect on the environment (McDonough, Braungart, 2002). The current model of construction, maintenance, and demolition that most buildings go through ignores the resources and materials that are used and discarded, creating by-products that can never be used again by humans or the natural environment.

In order to align programmatic lifecycles with building creation and material decay, architects must incorporate decay in design, allowing building materials to continuously support human and biological use when a building is abandoned or demolished (figure 0.1). All buildings must die, but their material by-products do not need to be wasted. Incorporating decay is an opportunity for the future growth of architectural spaces and realigns the buildings that we make with the natural cycles that affect them. Therefore, to explore this potential, and minimize the waste associated with a building’s decay or demolition, architects need to design buildings and urban landscapes with the eventual decay of products in mind, to eliminate wasted resources, and reinforce the existing natural cycles impacting our work.

To investigate this claim, this project will design a 2-story mixed-use structure, using fully biodegradable materials. This development type has a legacy in architectural practice and is a staple construction type of most major U.S. cities. It also acts as an advantageous operating system relative to this thesis due to its cyclical resiliency to programmatic cycles, and its need for continual replacement and maintenance of materials. This investigation is intended to relink human spaces with natural ones, fostering the perpetual growth and balance of both systems with each other.

Passing Permanence: Reversible Building Practices in the U.S. by Aaron Baldwin, M.Arch ‘23
Lawrence Technological University | Advisors: Scott Shall, M.Arch/RA, Sara Cordarin, Ph.D & Daniel Faoro March/UD, RA

The construction and demolition industries generate abhorrent amounts of waste through the inefficient generation and unplanned removal of permanently intentioned buildings that cannot last forever. Current strategies of material construction often consume, permanently alter or degrade materials being used, resulting in the inability to wholly reuse valuable building components. As a result, existing unused structures will often become waste, or require resource-intensive recycling or remanufacturing to salvage portions of material (USEPA 2018).

Buildings are not permanent. The current lack of life-cycle design and expectation for buildings to last indefinitely leads to a loss of “technical nutrient” potential (Braungart 2002). The reduction of waste, the continued reuse of materials and designing for component longevity can achieve a fundamental level of sustainability, as the concept of waste is antithetical to the ability to maintain a process over time. To recapture the potential of a building and remove the ecologically harmful effects of permanence that occur after the building is no longer needed, the production, construction, use and demolition of architecture should ‘leave minimal trace’ on its building materials and site.

A current lack of reversible and circular practice in the U.S. exists due to many existing social, cultural and economic factors. The focus on tradition, risk aversion and bountiful space for new development allows the country to remain stagnant and reliant on existing building methodologies without the push for change. Initial reversible architecture located in the U.S. will not be made out of newly developed components, but primarily of existing standardized materials joined in newly reversible methods.

Architecture should not be destructive. An architecture that leaves minimal trace does not have to employ highly engineered componentry and new modular solutions that restrict design outcomes but rather can modify existing techniques and tectonic understandings to remove wasteful practices that intentionally degrade or destroy material resources. Minimal trace architecture simultaneously upholds the health of its materiality through the redefinition of connection types while supporting its site and larger context through the removal of systemic inefficiencies and unnecessary permanently intended change.

2023 Study Architecture Student Showcase - Part XXV

Biomaterials are the central theme of the projects featured in Part XXV of the Study Architecture Student Showcase. From BioRock to mushrooms and mycelium, the showcased work goes beyond the traditional uses of biomaterials to propose alternatives that offer symbiotic outcomes by simultaneously solving architectural challenges and promoting sustainability.

Toronto’s Terrestrial Reefs by Cameron Penney, M.Arch ‘23
Carleton University | Advisor: Lisa Moffitt

Toronto’s Terrestrial Reefs explores the design potentials of BioRock, an underutilized accreting material that simulates the reef-building processes of corals. BioRock is a grown limestone, alternative to concrete with a design agency that has many positive benefits including its ability to act as an ecological scaffold, sequester pollutants, and be highly sustainable. This work proposes three speculative applications of BioRock within urban Toronto that go beyond the typical marine-based applications that this material has been historically restrained to. These include the reintroduction of Alvar habitats as a landscape strategy, the remediation of obsolete reservoirs for BioRock production, and the in-situ repair of concrete bents supporting the Gardiner Expressway.

­The research approach included material experiments, lab work, and data analysis. A series of experiments were conducted that tested various morphologies and growing conditions within a self-made wet lab. This means of working developed an understanding of the material from a hands-on perspective to speculate upon new uses for architectural design. Next, interviews were conducted with an interdisciplinary team of consultants which promoted conversations between research in material ecology and landscape ecology. First, a Professor of Biology and coral reef researcher, Dr. Nigel Waltho. This conversation shed insight on BioRock’s limiting factors including its growth rate. Second, a Professor of Chemistry, Dr. Bob Burk, spoke to the practicalities of BioRock industrial-scale synthesis. Thirdly, an Electrical Engineer, Dr. Jianqun Wang from the Carleton Nano Imaging Facility lab. By working with Dr. Wang, material samples were analyzed under a scanning electron microscope to determine the type of BioRock produced, the relative strength of the material, and its capabilities in the repair of concrete at the nanoscale. Finally, a Landscape Ecologist, Dr. Jessica Lockhart from the Geomatics and Landscape Ecology Research Lab. Informed by the literature produced at her lab, a landscape strategy via a habitat network modeling script was developed.

The resulting design was explored through these experimental models and test fragments of BioRock which formed a library of artifacts that traverse biogeochemical scales of speculation, assembling a collection of work in the form of a Terrestrial Reef.

This project won the Maxwell Taylor Prize.

Hotel Elena by Kristi Saliba, B.Arch ‘23
University of Oklahoma | Advisor: Amy Leveno

Viva Terlingua!

The initial phase of this fifth-year undergraduate studio will run as part science lab/part sculpture studio/part fabrication shop. Students will break up into teams to research, explore, and document the process of creating hempcrete through hands-on explorations. 

The second part of this studio will explore the role of natural building and hospitality through the design of a boutique hotel in Terlingua, Texas, a town just outside an entrance to Big Bend National Park. Students will work in teams to create a building that responds appropriately to the harsh beauty of the surrounding landscape through high design with a focus on natural building systems and sustainability. Students will also select their individual project sites around the area, define their target clientele, and craft a program that appropriately serves that site and demographic.

Knitting together the first and second parts of the studio will be the fabrication of a full-size wall section demonstrating how hempcrete is utilized in a typical wall section.

Fungus Among Us by Yitao Guo & Kinamee Rhodes, M.Arch ‘23
UCLA Architecture and Urban Design | Advisor: Simon Kim

Architecture of the future will be built with mycelium – the root structure of fungi. Mycelium is a renewable building material, currently in an experimental stage in the form of lightweight bricks, insulation, and flooring. This facility is dedicated to expanding the possibilities of this material, envisioning a post-anthropocentric world of mycological architecture. A forest of bent steel creates a pliant stack-floor building with post-into beams that allow for bounce and deflection. A bio-tunnel for cultivation and circulation intersects with the big-box typology. The spaces inscribed but never enclosed in the building reference Archizoom, lshigami, and Toyo Ito with their extensibility and density. Ultimately, the orchestration of sloping slabs and inside/outside structural clusters is a re-imagination of the principles of a myco-Raumplan.

Learning From Yucatan by Anna Hartley & Maggie Jaques, M.Arch ‘23
Kansas State University | Advisors: David Dowell, Ted Arendes, Salvador Macias, Magui Peredo & Diego Quirarte

LEARNING FROM YUCATAN: EXPLORATION JOURNEY THROUGH A SUSTAINABLE IDEA OF PLACE

Mexico is a very diverse cultural and natural mosaic. We have had the opportunity to work in several parts of the country, from our location in Guadalajara. Somehow we have worked as “foreigners” in our own country. However, from that foreign perspective, we have found particularly in the Yucatan Peninsula a place of enormous learning and a source of inspiration that continues to captivate us.

This region of the country is one of the most prolific in its biodiversity, abundance of natural resources, and extraordinary cultural past.

The Yucatan Peninsula witnessed the flourishing of the Mayan Culture. In Yucatan, a large part of the population today is still Mayan. Despite having more than two thousand years of existence, the Mayan communities still speak the original dialect, they give continuity to the gastronomic tradition, and above all, keep on living the same way: in small complexes that become a house, a bedroom, a garden, an orchard, a farmyard, a kitchen, etc. This fascinating and sustainable phenomenon has attracted and moved us deeply.

All of this has made the Yucatan Peninsula a huge international tourist magnet, but also a place of pilgrimage for contemporary life that seeks a sustainable, peaceful way of life, connected with nature and respectful of the environment. As if the Mayan way of life, in a certain sense, began to be “adopted” as a way of life by followers of their culture.

In 1972, Robert Venturi and Denise Scott Brown published “Learning From Las Vegas,” the research project they made with their students understanding the city. Calling for architects to be more receptive to the ordinary and to overcome the forgotten idea of “symbolism” in modern architecture at the time.

The studio attempts, through the title, to recall this model of study and tries to provoke students to board on a similar journey of exploration. Like a foreigner who tries to examine a new and adverse territory, and interact with it without prejudgment in order to learn from it. That is why we introduce one of the many drawings that Frederick Catherwood made when he joined the American explorer John Lloyd Stephens on his discovery journey of the Yucatan Peninsula in 1839 and that they would publish in 1841.

From the learning and the reflection, we will invite students to produce contemporary ways of living based on the principles, the ways of life, the local conditions, and the ways of making this unique place.

This project won the 2023 Kremer Prize for Best Group Project.

BacTerra: Designing Across Scales by Claire Leffler & Kimia Bam Farahnak,B. Arch,  MAAD ( M. Advanced Arch Design) ‘23
California College of the Arts, Architecture Division | Advisors: Margaret Ikeda, Evan Jones & Negar Kalantar

The research goal of BacTerra is to investigate the potential for a biomaterial to reduce embodied carbon in building components and to be accessible to communities around the world. Many animal species have the capacity to form hard shells which rely on chemical and biological reactions. This serves as a model for how to avoid the intense heat energy required for industrial building materials like concrete and bricks. Cement-based concrete production is responsible for 8% of total Co2 emissions per year, meanwhile, plankton, mollusks and birds are all capable of fabricating shells through the precipitation of calcium carbonate from their environment efficiently and without hazardous output. Utilizing these species as a source of inspiration the student research focused on leveraging these biological processes to produce bio-mineralization in a mixture that combined clay, a safe and widely available B.Subtilis bacteria, sea urchin shells (a calcium carbonate local resource), and extruded fabrication at the scale of architectural components.

This thesis was a BioDesign Challenge top 8 finalist and received the Outstanding Science Award.

MUTUALISME, Symbiotic bio-organization at the service of a living program by Anaïa Duclos, M.Arch. ‘23
University of Montreal | Advisor: Andrei Nejur

This project uses architecture to slow down the intensive transformation of territory by the food production sector. Between 2019 and 2020, 1,362,000 tonnes of construction waste were discarded. This represents 28% of all landfill waste in Québec. Gypsum board partitions are extremely prevalent in buildings and urban environments, but they are also highly polluting. During their deconstruction, they are mostly thrown away and buried in landfills.

The project reappropriates gypsum board partitions to create a productive wall, thus slowing down the transformation of the territory. It addresses a new vital human need beyond that of housing, it provides food as well.

The living program is defined by the production of mushrooms through the structure of the traditional gypsum board partition. It infiltrates unused space and adapts to optimize its surface within a given area. Cracks and folds in the structure increase the surface area where mushrooms can grow. The human program offers workshop rooms on mycelium and its usage, creating a learning center for mycomaterials. Surrounding this program where human activities take place, is the living program in constant growth.

The process enriches the neighborhood users as well as the living program. Local residents bring their waste to the learning center, which serves as a substrate for the mycelium to enhance production. The transformed mycelium can then be collected by visitors, and the mushrooms are harvested for consumption. The result is a symbiotic relationship and mutual enrichment at the heart of the city.
